Inventor: CHEN YOUNG-KAI
IPC: H01L29/08

Abstract: Improved heterojunction bipolar transistors (HBT) are disclosed. Inventive devices can attain high cut-off frequency (f T ), exemplarily 80 GHz or higher, and high DC current gain (β), exemplarily 25 or higher. The devices exhibit lateral scaling, permitting reduction in emitter stripe width without unacceptable decrease in β. Exemplarily the strip width is 1 µm or less. The inventive HBTs are hot electron devices, with the hot electrons in the base region (13) being spatially confined such that relatively few electrons reach the surface of the extrinsic base region. The relatively low bulk and surface recombination rate in the base of inventive HBTs is an important aspect of the invention and makes possible devices having relatively high β and low power consumption. Appropriate choice of base material, namely, a semiconductor material having relatively low intrinsic surface recombination velocity, can result in further reduction of surface recombination, as can, for instance, the use of an appropriate non-alloyed metal base contact. Appropriate choice of collector material can result in improved ballistic transport through the collector depletion region (14), and novel selection criteria are disclosed. InP, InAs, and In 0.53 Ga 0.47 As are exemplary materials that meet these criteria. Use of a highly doped collector contact region (18), with dopant level within a relatively narrow concentration range, can also lead to improved device behavior, as can the use of a compound emitter (12) that comprises one or more appropriately placed thin undoped heteroepitaxial layers.

Abstract: An equalizer apparatus is to be applied to a disk recording medium of DBF, for which there is used a sampling clock reproduced from the clock pit recorded on a disk recording medium. A fixed equalizer block comprising an analog to digital converter, a memory and a two-­dimension equalizer suppresses the wave interference from the adjacent tracks and can reduce the error rate of the reproduced data by cross-talk even in case of narrowing of the track pitch. Further, by adding to the equalizer a sign detector, an FIR low-pass filter and a coefficient control circuit to make it a blind equalizer block, the interference fluctuation attributed to linear recording density, recording power irregularity, light spot, tracking error, etc. can be automatically compensated to suppress such fluctuation. Further, By the construction of the blind equalizer block, the errors of clock timing and its fluctuation can be automatically compensated with good efficiency.

Abstract: In a switch mode power supply (200), a first switching transistor (Q2) is coupled to a primary winding (W₁) of a transformer (T2) for generating pulses of a switching current (i₂). A secondary winding (W₂) of the transformer is coupled via a switching diode (D3) to a capacitor (C4) of a control circuit for developing a control signal (V₄) in the capacitor (C4). The control signal (V₄) is applied to a mains coupled chopper second transistor (Q1) for generating and regulating supply voltages in accordance with pulse width modulation of the control signal (V₄). During standby operation, the first (Q2) and second (Q1) transistors operate in a burst mode that is repetitive at a frequency of the AC mains supply voltage such as 50Hz. In the burst mode operation, during intervals in which pulses of the switching current occur, the pulse width and peak amplitude of the switching current pulses progressively increase in accordance with the waveform of the mains supply voltage to provide a soft start operation in the standby mode of operation within each burst group.

Abstract: A circuit capable of being integrated into a self-isolated DMOST is driven by a sense resistor that is created from the DMOST drain metallization. The circuit produces an output current that is ratioed with respect to the DMOST current with the ratio being determined by the value of a single resistor. The output current is sourced when the DMOST conducts its source current and the output current is sunk when the DMOST shunt diode conducts. Thus, the circuit not only produces a DMOST current related output it also distinguishes the mode of DMOST conduction.

Abstract: A food refrigeration system (10) for refrigerating articles of, for example, food, includes at least two cooling stages formed by a water cooler (14) and a cryogenic freezer (16). The cryogenic freezer (16) receives the articles of food and transfers heat from the articles of food to a liquid cryogen (liquid nitrogen) so that the articles of food are refrigerated. The transfer of heat from the articles of food to the cryogen causes the cryogen to boil and thereby evolve a cryogenic vapour. The cooler (14) receives the articles of food prior to the cryogenic freezer (16) and transfers heat from the articles of food to the cooling water. Such heat transfer reduces the quantity of cryogen required to refrigerate the articles of food. An eductor (50) is connected to a pump (62) and to vent duct (72) from the cryogenic freezer (16). The cooling water is pumped through the eductor (50) to suck cryogenic vapour from the cryogenic freezer (16) and to mix the cryogenic vapour and the cooling water prior to reception of the cooling water in the cooler (14). Such mixing transfers heat from the cooling water to the cryogenic vapour resulting in an increase of the heat transfer between the articles and the cooling water in the cooler (14). As a result of such increased heat transfer, the amount of cryogen required in refrigerating the articles is reduced.
